Oral use. Administer in drinking water.

Revised: September 2025
AN: 01877/2025
Pigs:
The dosage is 8.8 mg of the active substance per kg bodyweight daily, (equivalent
to 10 ml solution per 142 kg bodyweight) administered in the drinking water of pigs
for 3 to 5 days, depending on the severity of the infection and/or the duration of the
disease.
To ensure an intake of 8.8 mg/kg daily it is important to know the weight of the
animals to be treated and to measure accurately their drinking water consumption.
Administer the calculated dose (based on the animals weight) in approximately
one half of the daily water requirements, to ensure consumption of the correct
dose. Unmedicated water should then be provided each day after the medicated
water has been consumed. The dosage rate, calculated on a liveweight basis, is
equivalent to 10 ml solution per 142 kg bodyweight.
Where a water medicator is used the appropriate stock solution should be made
up according to the makers instructions.
Any medicated water not consumed within 24 hours should be discarded.
If there is no response to treatment within 5 days, the diagnosis should be re-
established.
Monitor water intake at frequent intervals during medication.
Fresh solutions of tiamulin-medicated drinking water should be made up each day.

Do not administer products containing monensin, salinomycin or narasin during or
for at least 7 days before or after treatment. Severe growth depression or death
may result.

On rare occasions erythema or mild oedema of the skin may occur in pigs
following the use of tiamulin hydrogen fumarate.

In order to avoid interactions between tiamulin and the incompatible ionophores
monensin, narasin and salinomycin, the feed mill supplying the feed should be

notified that tiamulin will be used and that these products should not be included in
the feed or contaminate the feed.
The feed should be tested for the ionophores prior to use if there is any suspicion
that contamination of the feed might occur. If an interaction does occur, stop
tiamulin water medication immediately and replace with fresh water. Remove
contaminated feed as soon as possible and replace with feed not containing the
tiamulin-incompatible ionophores.
